Deadpool 3 vs Spider-Man

According to a portugese site, Tom Holland wants to be in Deadpool 3 as Spider-Man. The idea is fantasic since there could reside continuity in such thing and also follow comic book timelines. But with the Sony rights behind our backs, where Spider-Man is currently just borrowed to the MCU, how possible would this be to really happen?

According to the above linked site, there are also (very loose) rumours about Deadpool 4 in development which also is mentioned here. The rumour has been started by an insider – Daniel Richtman – at Patreon. But for a real confirmation, we’d have to wait.

There are neither any indication of the Spider-Man/Deadpool scenario happening anytime soon, but according to the insider Daniel Richtman, Tom Holland had shown the interest in Deadpool 3.

How did Deadpool know about Logan?

I’ve been thinking of the timeline after reading an article from itechpost that also matches with the data on https://mcu.earth616.org.

It states the order of how Deadpool 2 and Logan plays out together in chronological order. This said, it’s been quite a mission to complete the “occuring movie years” for the X-men Legacy since Fox practically destroyed the timelines with reboots and such – and I’m much aware of the fact that Deadpool 2 occurs long before Logan.

I’m of course also aware of the default 4th walling here and that Deadpool might know about those events due to this. And I guess that there has been quite a time traveling, according to the post credit scenes since then. But shouldn’t this occur in some kind of reverse order? If Deadpool 2 begins with a “Death of Logan” reference, and ends with Deadpool time traveling – how could he possibly know?
